    FULLTEXT relevance algorithm?

    Hi,


    I've just started to implement a FULLTEXT search script in PHP. I have
    read that the relevance rating should not directly be used to create a
    rating (as a percentage say) for the results you may return to a user.

    Is there an effective algorithm whereby some normalisation etc. could
    effectively be used to provide at least a "rough" guide?


    TIA

      You might want to take a look at "The Anatomy of a Large-Scale
      Hypertextual Web Search Engine" by Sergey Brin and Lawrence Page
      (yes, they are indeed Google founders):
